Abstract (en)
Provided is a polycarbonate-polyorganosiloxane copolymer having high transparency, which is obtained by an approach except an interfacial polymerization method.The polycarbonate-polyorganosiloxane copolymer, which is produced by using a diol monomer (al) and a polyorganosiloxane (a2) satisfying the following condition, includes: a polyorganosiloxane block (A-1) including a specific repeating unit; and a polycarbonate block (A-2) formed of a specific repeating unit: a mixture, which is obtained by bringing the diol monomer (al), the polyorganosiloxane (a2), a carbonic acid diester, and a basic catalyst present at the same amount ratio as that at a time of production of the polycarbonate-polyorganosiloxane copolymer into contact with each other at from 100°C to 250°C for from 0.5 hour to 5 hours, has a haze value of 30 or less measured under conditions of 23°C and an optical path length of 10 mm in conformity with ISO 14782:1999.
